How can I use a computer to flash techno canon c9
well you can't. rooting is very device specific. you can try some one click root like kingo root, but i'm not sure it will work. you picked a device that is not supported by developers and thus nobody has worked on a way to root.
the only question i have for you is why do you want to root? if the answer to is to remove bloatware or something to that effect, i would caution you. give me a sec as i will explain, but there are a few things that need to be said.
first off, since there are not any developers supporting your device, you will not get a custom recovery. this is a very important to tool for root users. a custom recovery can do many things, but one of the main functions is to make a nandroid backup of your phone. this is like a save point in a video game. if you mess up, you can always restore a backup and it will be like nothing happened to your phone. it backs up pretty much everything including your data.
second, if you want to root to delete things, then i would caution you. a lot of system apps are intertwined with each other. if you delete one, you might screw the other and it is quite possible you might make your phone inoperable (basically a soft brick). you might be able to fix it by flashing a firmware, but there is a possibility it will unroot the phone. (provide you do gain root).
and lastly just remember this:
no devs=no fun
the coolest part of rooting is the custom roms. there are so many talented developers out there. and we are all lucky that they are able to provide their hard work to the public.....pretty much for free (though i do recommend pitching in if they have an avenue for contributions). these custom roms are amazing: some are really small in size giving you more internal storage; some are optimized to be fast and provide better battery life; some are themed; and some are just rooted but stock.
and here is a tip:
if you are looking to root your next phone, do some research first. the best place to go for all things root is over at
xda developers forum. do a search for the phone you are interested. if you see that your phone has a forum, that is a great start. if you do not then i would stop right there. that means that there is no dev community for your phone. like i said no dev= no fun. if your phone does have a forum then start your research in the android development subforum. there should be guides on how to root the device.
and the last tip i will give is to read, read, read, and then read some more. at this point if you have questions please feel free to come back here and ask away. the main takeaway is to do your research first before making the plunge.
so as of right now there is no written way to root your phone. you might get lucky and kingo root or other older root methods might work, but i do not know. if you are still planning to root your device, then good luck and just be cautious.
